登陸小程序后臺(tái)https://mp.weixin.qq.com/更新一下用戶隱私協(xié)議
要填寫獲取相冊(cè)權(quán)限是干什么用的代碼里面也要判斷用戶是否有相冊(cè)權(quán)限
不然用戶一臉懵逼乍炉，只知道圖片保存無反應(yīng)獲取失敗
/**

uni.downloadFile({

// 下載成功邑滨，保存圖片到系統(tǒng)相冊(cè)
uni.saveImageToPhotosAlbum({
filePath: downloadResult.tempFilePath,
success: () => {
callback && callback()
uni.showToast({
